16 REQ#29 The MGW should support the DS3, No Can you please confirm having active DS3 links in the live network 17 REQ#45 The solution shall be able to generate Call Detail Records (CDRs). The CDR shall contains at least the following key fields: Calling party Called party (as received) Destination party (as sent out, e.g. after ENUM query) Incoming route Outgoing route Seizure time (date and hour) Answer time (if applicable date and hour) Media type (for audio, video and events) Release time (date and hour) Releasing party Release reason (a SIP error code and/or ISUP release cause) There is a mistake in typing, it is not ADR, it is CDR. Please describe your solution. Please indicate which functional element in your architecture will be responsible to create the ADRs.

Question: The expected behavior is a part of access SBC (class 5 ). Not applicable in desired solution. Please share your vision. 28 REQ#239 The centralized routing engine shall support role based access control and full audit trail Question: What is role based access control? 29 REQ#244 The centralized routing engine shall support zone routing Question: what is zone routing? 30 REQ#245 The centralized routing engine shall support US domestic and jurisdictional routing by LATA and state: Question: What is meant by state? In computer systems security, role-based access control (RBAC) is an approach to restricting system access to authorized users. Trunks can be grouped under different zones and if required, trunks will be available only within assigned zones or zones can have priority over other zones. Routing is overwritten by these rules where necessary. LATA stands for Local Transport and Access Area. A LATA is a contiguous geographic area. LATA is your local calling area. Therefore intralata means the same thing - your local calling area (inside a particular LATA). A LATA can cover an entire state so all the state will be considered intralata, and all calls within that state will be considered local calls (usually for small states). Most states have several LATAs. InterLATA refers to calls between 2 LATAs. These can be 2 LATAs located in the same state, or 2 LATAs located in different states. Therefore long distance calls. Interstate calls are calls between two states. These calls can also be considered interlata because they are calls between 2 LATAs. Intrastate calls are calls within the same state. This term is rather confusing because calls within the same state can be
31 REQ#253: The centralized routing engine shall support for different egress routing types based on combinations of SIP Trunk Group, DNIS Tech prefix, and IP Addresses of Provider Gateways Question: What is meant by DNIS Tech prefix and IP Addresses of Provider Gateways? 32 REQ#257 The routing logic engine shall support rule based automated route policy management Question: Requirement not understood. Can you please explain business driver and use case (example) 33 REQ#260: The routing logic engine shall support preventing cherry picking: Question: what is cherry picking? Can you explain the business driver and use case? either interlata or intralata. This is about how to differentiate carriers. Let s tag carrier A with 3333 and carrier B with 4444 prefix. Or instead only IP address of gateways can be used. If it s a shared IP, a combination of IP and tech prefix can be used in order to identify carriers. Additional routing logic should be able to be added to providers selection in a short term. For example, checking local number portability data table before applying route logic. Or applying translation rules based on trunk before applying the route logic. If in supplier cost sheet, let s assume the buy rates are like follows: 90 0.3$ 905 0.2$ 9051 0.1$ 9052 0.1$ 9054 0.1$ 9055 0.1$ 9056 0.1$ 9057 0.1$ 9058 0.1$ 9059 0.1$ 34 REQ#270 The routing logic engine shall support fetching of automated updates Question: Not understood. Can you explain the business driver and use case? 35 REQ#275 The billing server shall support integrated configurable supplier rate importing with routing Question: Can you clarify who is the supplier and the business driver and the use case? If customer offer to 905 is 0.25$, this supplier will not be used and discarded. Because 9053 is not offered and the cost of 9053 calls will be 0.3$ which will cause 0.05 negative margin. This is just the application s auto update functionality, not related with routing. Offer to customers are managed with a fixed format. But suppliers offers are all different formats, there s no standard. System comes with a wizard to normalize different pattern of
36 REQ#277 The billing server shall support general ledger both for prepaid and postpaid interconnect carries with all in and out data Question: since the ISS (IGW Node) does not have the end customer information, what is the aim to differentiate the prepaid and postpaid calls? This information will not be available on most of the cases. Or are these the prepaid postpaid customers mentioned here as the carriers getting service? If so, can you clarify for the prepaid use case? 37 REQ#278 The billing server shall support SoA (statement of account) Question: We understand as, the account mentioned here is the carrier customers accounts, can you confirm? cost sheets. This is not class 5 level. Payment models are related with class 4 arbitrage models. Existing models are prepaid, postpaid, or postpaid with credit limit which is very similar to prepaid. If operator will only allow to a carrier to populate calls with a prepayment only, this is prepaid. It can be done through a cash transfer or setting a credit. After calls are accumulating, outstanding balance will run out and should be replenished. Yes 38 REQ#312 The shall offer equipment with minimum 3 years support packets. Question:Can you please clarify what is meant by 3 years support packets 39 REQ#1 SIM Box detection service should include a limitless number of countermeasures to avoid that fraudsters detect the test calls. Following countermeasures are included and will be customized and optimized in accordance with the specific situation in the country: Question: In the normal flow of the SIM Box usage, the calls are not expected to go over the ISS lines, instead go over the IP connections as VoIP calls until they are handed to the local operator s network via SIM Box. Hence, it doesn t seem to be practical to try to detect the SIM Box fraud on ISS network. Can you clarify the cases that you would like to prevent? 40 REQ# Core Router Question-1: Card Redundancy is not mentioned in RFP for Core Router? Alcatel-Lucent concern is there should be card redundancy as well in case of any failure as the whole IMS IP Router structure will be single point of failure. 41 REQ# Core Router Question-2: there aren t any GE, 10GE, E1, E3, STM-1, STM-4, STM-16 port quantity requirements for Core Router in RFP. The type of cards and the minimum quantity of port requirements are not defined. What are the minimum GE, 10GE, E1, E3, STM-1, STM-4, STM-16 port numbers?
